Although I am not aware of Sundial books written SPECIFICALLY for
children, several (mainly Analemmatics due to their 'interactive'
nature) are certainly featured within some School-books - and you
could view examples at website: www.sunclocks.com/data/school.htm
If you want to interest children in the subject of Sundials - then
I suggest that you visit some Schools and give a 'presentation' to
them - as in the attached photograph, showing Slaven Licina giving
such a talk. You can visit his own website at: www.suncanisat.com
